Extrosheaited Pain

The pain is in near danger! It is a code-red time for your race. Your race has been dieing out for several years and is about to become extinct. Use your mighty powers to compete against your predators to save your kind. Moreover, if you don't, your whole race or even your whole species may die out! Just use your hunched over back for the one because you are an Aushtrolupothicus on this mission! But, you have weapons from the Neolithic Era, and some from the Paeloithic Era.
